> Traffic control system for
Thuringia: coordinated traffic
control with six integrated tunnels
The supervisory traffic control system for Federal
Motorway A71’s Thuringian Forest Kammquerung
section was created by Heusch/Boesefeldt GmbH,
under subcontract to QSG Verkehrstechnik GmbH,
as the first system in Thuringia. The Eichelberg
A71 Tunnel and Jena A4 noise protection system
were integrated as an interim step. A subsequent
extensions resulted in the establishment of a “supervisory
traffic control system”.
The traffic control system is a server system comprising
two redundant units. Each unit consists of
a data base processor and an application and user
server. The systems work in “hot standby” mode
this way.
The traffic control system manages the traffic
taking into account information from the six integrated
tunnels’ operations equipment. For this
purpose, the traffic control system is connected to
the tunnel computers of the six individual tunnels
and the supervisory control computer. The servers
receive aggregated information from the traffic
control system.
Traffic data is collected in 15 seconds intervals via
the attached sensors.
Disasters across multiple tunnels are dealt with
in a coordinated way supported by appropriate
rerouting measures over subordinate nets. The
rerouting alarm indication occurs via the rerouting
system’s automatic circuitry.

> safety measures during malfunction: immediate
lane closure or complete tunnel closure
> detour measures during tunnel closure
> speed regulation dependent on the situation in
the tunnel (traffic jam, flat tire, etc.)
